Sorry it took me so long to respond...as far as the Mothership, if you had the 100's at +1 1/2, I would go +.5 or right on the line. This ski is PERFECT on the line. I skied my 100's at -1cm, though, so I may be biased. Personally, with the slight rocker in the tip, I would ski them on the line as you are losing a few cm of contact at the front on the snow.

I had about 30 days on the 195's last year, and about 10 so far on the 185...I am 210lbs and bomb everything I can, and the 185 is perfect on the mounting line.

hope that helps
